Sample GSM4952865 Query DataSets for GSM4952865
Status Public on Dec 02, 2023
Title ChIPseq_WSN_24h_rep1_H3K27Ac
Sample type SRA
Source name Calu3
Organism Homo sapiens
Characteristics agent: Influenza
time point: 24h
antibody: H3K27Ac, Diagenode (C15410196)
Extracted molecule genomic DNA
Extraction protocol Calu3 cells were infected with Influenza or SARS CoV-2 virus for various time points before harvesting them for chromatin profiling. The ChIP-seq library preparation was done as in Arrigoni et al. Communications Biology (2018).
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
Description ChIP-seq
Data processing ChIP-seq reads were aligned to the human genome build hg38 using the ChIP-seq module from the snakePipes package (Bhardwaj et al., Bioinformatics, 2019). Duplicate and discordant reads were removed. Peak calling was done with MACS2 (model- based analysis of ChIP- Seq) (Zhang et al., Genome Biol, 2008) using "--keep-dup all", "--nomodel", "--extsize". Gene annotations and transcript start site (TSS) information for human genes were from taken from Gencode annotation release 31. Reads overlapping the TSS regions (TSS +/- 100bp) were counted using bedtools2 (Quinlan & Hall, Bioinformatics, 2010). Differential analysis of TSS density was done using DESeq2 (Love et al., Genome Biol, 2014). Size factors were calculated based on the signal in genomic bins of corresponding Input samples similar to (Arrigoni et al., Communications Biology, 2018). Profile plots were generated using deeptools2 (Ramirez et al., Nucleic Acids Res, 2016) using bigwig files that were normalized using the size factors calculated based on the corresponding input samples.
